High perfomance In-Memory DBMS


Globally, ALTIBASE HDB has been used at over 3,000 sites in the past 13 years, and more than 2 billion transactions in a day are successfully processed. Prominent customers include Samsung Electronics and POSCO in South Korea, China Unicom, China Telecom, and China Mobile in China, Toshiba and Mizuho Securities in Japan, and many more.


Altibase Corporation is a privately owned enterprise database management system vendor with offices in Seoul, Palo Alto, Beijing and Singapore. Altibase is privately owned and has demonstrated consistent year-on-year revenue growth since its foundation in 1999.


Over 400 customers at over 1000 sites are using ALTIBASE HDB for mission-critical OLTP applications, particularly in the telecommunications and financial sectors. All three major Chinese telecoms operate Altibase servers as billing servers. In South Korea, Altibase holds almost 90% of the in-memory DBMS market share across all industry verticals.


What is In-Memory Computing?


The field of in-memory databases is an interesting one that has been widely researched since the early 1980s. When the Internet era began in 2000, the need for high-performance data processing was increasing especially in telecommunications, finance and manufacturing areas. About that time, in-memory DBMSs were made commercially available in the world.


The most well-known commercial in-memory DBMSs were TimesTen from the US, Solid from Finland, and ALTIBASE MMDB from South Korea. Later, TimesTen was acquired by Oracle, and Solid was acquired by IBM. All tree in-memory databases were specialized in OLTP (On-Line Transaction Processing) performance for processing massive amounts of transactional data which was not possible by using traditional disk resident databases.


Before in-memory DBMS technology was developed, many companies developed their own in-house solutions using techniques like shared memory and so on, to work around the shortcomings of traditional disk resident databases. Those companies were the early adopters of in-memory databases, taking advantage of the benefits gained from the convenience and ease of management.


What is ALTIBASE HDB?

HDB stands for Hybrid DataBase. ALTIBASE HDB combines an in-memory database with a conventional disk-resident database.


The benefit of using an in-memory database is high data processing performance. Especially in an OLTP environment, it can guarantee consistent response times. Its limitation is that the size of the database is limited by the amount of main memory in the system. However, this limitation can easily be overcome by ALTIBASE HDB, because it also comprises a disk-resident database. The ability to access an in-memory database and a disk database using single engine is a unique solution that service providers can take advantage of.


With these advantages, ALTIBASE HDB is suitable for use in the communications, securities and medical equipment fields, where performance and functionality are paramount.
